Economical Micro Vickers Hardness Tester for Glass Steel Metal Coating Manual Type HV-30
The manual turret type Vickers tester can meet the basic Vickers hardness test requirements.the upgraded control system can provide more measurement data, and the control is more comprehensive and accurate.
Main Function and Feature:
1. The optical system designed by senior optical engineers not only has clear images, but also can be used as a simple microscope, with adjustable brightness, comfortable vision, and not easy to fatigue after long-term operation;
2. The industrial display screen can directly display the hardness value, convert the hardness, test method, test force, holding time, measurement times, and the test process is intuitive and clear;
3. The cast aluminum shell is formed at one time, the structure is stable and does not deform, the car paint grade is high, the scratch resistance is strong, and it is still bright as new after years of use;
4. Our company has the ability to research, develop, design, produce and process by ourselves, and provide parts replacement and maintenance upgrade services for our machines for life;
Main purpose and scope of application:
1. Steel, non-ferrous metals, metal foil, cemented carbide, metal sheet, microstructure, carbonization;
2. Carburizing, nitriding and decarburizing layer, surface hardening layer, electroplating layer, coating, heat treatment;
3. Glass, wafers, ceramic materials;
